yes / A large number of cloud middleware platforms and tools are deployed to support a variety of Internet
of Things (IoT) data analytics tasks. It is a common practice that such cloud platforms are only used
by its owners to achieve their primary and predefined objectives, where raw and processed data are only
consumed by them. However, allowing third parties to access processed data to achieve their own objectives
significantly increases intergation, cooperation, and can also lead to innovative use of the data. Multicloud,
privacy-aware environments facilitate such data access, allowing different parties to share processed
data to reduce computation resource consumption collectively. However, there are interoperability issues in
such environments that involve heterogeneous data and analytics-as-a-service providers. There is a lack of
both - architectural blueprints that can support such diverse, multi-cloud environments, and corresponding
empirical studies that show feasibility of such architectures. In this paper, we have outlined an innovative
hierarchical data processing architecture that utilises semantics at all the levels of IoT stack in multicloud
environments. We demonstrate the feasibility of such architecture by building a system based on this
architecture using OpenIoT as a middleware, and Google Cloud and Microsoft Azure as cloud environments.
The evaluation shows that the system is scalable and has no significant limitations or overheads.
